采用高速度和可与束流直径相比拟的偏摆量按不同轨迹偏摆电子束,是保证提高焊接接头质量的有效工艺措施。广泛采用的有电子束沿焊缝纵向和横向,以及按圆周旋转的偏摆。对其它各种类型的轨迹研究表明,采用 X 形轨迹偏摆电子束,在选用最佳偏摆频率的情况下能达到最大的效果,可在熔深减小极少的情况下大大减少焊缝根部缺陷。按其它轨迹偏摆电子束,往往应用专门的模
The use of high-speed and beam diameter can be compared with the deflection according to different trajectory deviation electron beam, is to ensure the quality of the welded joints to improve the effective technical measures. Widespread use is the electron beam along the weld longitudinal and transverse, and according to the rotation of the yaw. Various other types of trajectory studies have shown that the use of X-shaped trajectory deflection electron beam, in the optimal use of the yaw frequency of the case can achieve the maximum effect, can be reduced in the case of very small weld seam reduction Root defects. By other trajectories of electron beam deflection, often use a special model
